Design and Implementation of Efficient Analysis and Synthesis QMF Bank for Multicarrier Cognitive Radio Communication
Abstract: The present section
deals with a new type of technique for designing an efficient two channel Quadrature
Mirror Filter Bank with constant phase in frequency. For achieving the Perfect
Reconstruction Condition in Filter bank, an attempt has been made to design the
low pass prototype filter with its impulse response and frequency response in
three regions namely pass band, stop band and transition band region. With the
error in terms of Reconstruction and the attenuation in the stop band as seen
in the prototype filter response, one can evaluate the performance of the
introduced filter with the help of filter coefficients generated in the design
examples that affects the quality of filter bank design under the constraints
of Near Perfect Reconstruction Conditions.
